ACME Tornado 2000 pilli
Tornado 2000 is the world's loudest whistle. Its unique design (without 'pea') produces a high frequency tone, which penetrates even very loud background noise and a low frequency pitch which can be heard at great distances. Unsurpassed and, in the meantime, employed not only by S.O.L.A.S. rescue operations but by all forms of sporting functions eg. the Champions' League (F.I.F.A.). Naturally, waterproof and only 10g light. Signal orange.
